do you know how to do proofs

anonymous · Answer

Eh... Not very well

juicstice · Answer

okay well I haven't done one for over a year but I still got some stuff that I could tell you. tbh I kinda miss proofs

anonymous · Answer

Alrighty

anonymous · Answer

Haha nice

juicstice · Answer

Angle DBE is ~ to angle ABC because vertical angles are ~

anonymous · Answer

Ok

juicstice · Answer

Angle CAB is ~ to DBA. I don't remember what the theorem is called but I know that is ~

juicstice · Answer

so we have 2 angle that are ~ so that means we only need a side to be ~ to solve this. Do you think you could tell me what that side is?

anonymous · Answer

DEB?

I've got all I need from here, I got the question, thank you!

juicstice · Answer

I'll give it away and say that the reason these triangles are ~ is because of ASA. the sides that are going to be ~ are side AB and side BD. I'm sorry but I know what I'm doing I'm just having a hard time remembering what the name of the reason is called

anonymous · Answer

I know, thank you for all of your help! Geometry can be confusing. But I got it! :)

juicstice · Answer

oh and a word of advice mark the triangle with the ~ signs that the your teacher probably told you. It helps so much

anonymous · Answer

Okay, I will! Thanks!
